The first step in PSA is to Fourier transform the image and calculate the square modulus of the FT to generate the power spectrum, . ... Specifically, one excludes the very lowest frequencies where the large scale nonuniformities in the image have the greatest effect, and one limits the fit to a frequency range where the SNR is sufficiently high. ...

2. Towards Optimal Analysis of HST Crowded Stellar Fields
... The improvement will be more pronounced in our crowded Wide Field Camera (WFC) images, and may be increased further through use of a more sophisticated method of combining the individual dithered images. Our analysis allows us to check for point spread function shape variations in the HST Planetary Camera (PC) field. ... In crowded field images, we are deriving information about the faint end of the luminosity function (LF) from the texture of the image background. ...

13. LHPP ISSP RAS
... High-pressures experiments are mostly aimed at studying phase transformations in solids, synthesising new phases and studying their composition, crystal and magnetic structure, physical and thermodynamical properties. ... The specific feature of investigations at LHPP that distinguishes it from most other high-pressure laboratories is combining in situ measurements with studies at ambient pressure of new high-pressure phases fixed by quenching to liquid nitrogen temperature. ...

14. Trapping operating system signals
. Shell procedures may use the trap command to catch or ignore Unix operating system signals . The form of the trap command is: trap ' command-list ' signal-list . Several traps may be in effect at the same time. If multiple signals are received simultaneously, they are serviced in ascending order. To check what traps are currently set use the trap command. For example: trap . Most common signals to be caught . Handling command lists . Examples .

16. Image quality-targets
Bar Targets . A limited number of bar patterns may be regarded as a continuous square wave pattern chopped by a rectangular pulse. ... For a 3 cycle target, the single-valued fundamental frequency of the square wave is replaced by a relatively broad band, centered near the fundamental frequency, but slightly below it, and moves nearer to it as the number of bars increases. ... This account is only true if the square wave extends indefinitely. ...

17. Armagh Observatory Preprint No. 306
... We present an analysis of an optical blue spectrum of the pulsating helium star V652 Her (=BD+13 3224$) in order to determine its effective temperature, surface gravity and chemical composition. ... The surface composition is characterised by abundances of nH=0.009, He=0.988, nC~0.000040, nN=0.0025 and nO=0.00010 (number fractions). ... If V652 Her was formed by the merger of two white dwarfs, its surface composition demands that they should both be helium white dwarfs. ...

... The effective temperature Te = 13700+ 500 and the surface gravity log g = 3.75 ± 0.25 were determined. ... It is shown that the ionization equilibrium for Fe I - Fe II and Mn I Hn II lines is maintained only for the second, more cool model. Out of 10 considered elements the largest overabundance was found for Mn (2.0 dex ), Ga (4.5 dex) and Hg (5.5 dex) . ... Hence it follows also that Y and Ce overabundance cannot exceed 2.5 dex. ...
